front end vibrates

This truck runs smooth when I get it started.:-) When I reach 50 mph the front end starts vibrating pretty bad. I have new tires. Besides that I really don't know what is causing this. Any help would be greatly appreciated.

Oh by the way I am running out of excuses to run out to the garage. I think my Wife is starting to suspect something. Man I love this truck!

Lift up the front of the truck and wiggle the tires. If they move you need new kingpins.

Braveduck, check out the radius arm bushings were the radius arm connects to the frame brackets. My 66 F100 had the same problem. My bushings were almost gone. Also if you have twin I beams check the pivot bushings. I replaced the pivot bushings and radius arm bushings with polyurethane bushings. I also replaced the front shocks with a set of gas shocks,Ryder Lts by Gabriel. Now I can let go of the wheel at 60mph without so much as a twitch. You will probably want to check the kingpins for any looseness while you are at it. I got my bushings from Autozone for about 40.00. JC Whitney also sells bushing kits for Ford trucks. I hope this helps. Post back if you have any questions.

Braveduck, Looks like you might have "my truck". 1966 F100 SWB 240cid. By the way, I live in Dallas also, Georgia that is. Good luck.

Must be common when these trucks get older. I am still very pleased with it. My first Ford was a 1965 Galaxie 500 Medium metallic blue. It had a 352 also. I never should have sold it. But i wanted a p/u.

Had similar problems with a 67 f100. I replaced the kingpins based on what everyone said it was. Didn't help. Finally put on new rod ends and this solved the problem. Mine did this to the point I could not hold the wheel. I could actually accelerate through it, it did this from about 50 to 60 mph, once I hit 60 it seemed to quit.
